Abstract

The present invention provides a system, method and apparatus for managing a wireless network in conjunction with an Ethernet switch comprising at least one SIP-aware application, an SIP-aware Access Port, and an SIP-aware management device for managing wireless network signals by providing out-of-band SIP signals to the SIP-aware Access Port. The device may comprise a program for load balancing SIP-aware applications and/or a port for monitoring all traffic across all ports. The invention provides for detection of rogue access ports, for the monitoring of RF link quality, Access Port availability and metrics for Quality of Service.

Claims

1. A computer readable medium containing instructions that when executed by a computer perform a computerized method for managing SIP-aware applications on a wireless network using an Access Port management appliance associated with an Ethernet switch comprising:

(a) identifying at least one SIP-aware Access Port in the wireless network to receive an SIP message;

(b) identifying an SIP-aware application associated with the at least one SIP-aware Access Port; and

(c) determining a route for Real-time Transport Protocol streams based the SIP-aware application associated with on the identified at least one SIP-aware Access Port.

2. The medium of claim 1 further comprising monitoring the SIP-aware application with the Access Port management appliance associated with the Ethernet switch.

3. The medium of claim 1 wherein a plurality of SIP-aware applications are load-balanced over a plurality of Access Ports.

4. The medium of claim 1 wherein the SIP-aware application is load-balanced across a plurality of Access Ports.

5. The medium of claim 1 further comprising monitoring the at least one Access Port to obtain measurements at least one of the group consisting of i) availability, ii) RF link quality and iii) Quality of Service.

6. The medium of claim 1 wherein the SIP-aware application is authenticated to the network via SIP messages.

7. The medium of claim 2 wherein monitoring the SIP-aware application with the Access Port management appliance associated with the Ethernet switch further comprises:

intrusion detection of a rogue access port.

8. The medium of claim 1 wherein an SIP-aware device is authenticated to the network via SIP messages.

9. A system for managing a wireless network comprising:

(a) an Ethernet switch;

(b) an SIP-aware application;

(c) an SIP-aware Access Port; and

(d) an SIP-aware Access Port management device associated with the Ethernet switch for communicating out-of-band SIP signals to the SIP-aware Access Port.

10. The system of claim 9 wherein the management device further comprises executable software for load balancing SIP-aware applications.

11. The system of claim 9 wherein the management device further comprises a port for monitoring all traffic across all ports.

12. The system of claim 9 wherein the SIP-aware Access Port is a Thin Access Port.

13. The system of claim 9 wherein the management device further comprises a program for detection of rogue access ports.

14. The system of claim 9 wherein the management device further comprises a program for monitoring RF link quality.

15. The system of claim 9 wherein the management device further comprises a program for monitoring SIP-aware Access Port availability.

16. A set of application program interfaces embodied on a computer readable medium for execution on a computer in conjunction with an application program that manages a wireless network Access Port management device, comprising:

(a) a first interface that receives an input for establishing out-of-band communication with an Access Port;

(b) a second interface receives an input for establishing monitoring port traffic on an Ethernet switch; and

(c) a third interface that receives an input from out-of-band aware applications associated with the Access Port.

17. The set of application program interfaces of claim 16 wherein the out-of-band communication is SIP communication.

18. The set of application program interfaces of claim 16 further comprising:

a fourth interface balancing out-of-band communication aware applications over a plurality of Access Ports.

19. The set of application program interfaces of claim 16 further comprising:

a fifth interface for detection of rogue access ports.

20. The set of application program interfaces of claim 16 further comprising:

a sixth interface for monitoring SIP-aware Access Port availability.
